Dimensional Analysis Activity

Part 1: Mole Map

Draw a Mole Map including the following: mass, volume (gasses at STP), particles (molecules,atoms), energy (heat in Joules), volume (solutions in Molarity), mole ratios

Part 2: Stoichiometry Problems

Steps to solve most stoichiometry problems:

1. Write the balanced reaction

2. Change to moles of known substance using menu (sometimes not needed)

3. Change to moles of unknown substance using mole ratio

4. Change to whatever the problem asks for (sometimes not needed)

Fe2O3 + 2Al ? 2Fe + Al2O3 ?H = -824 kJ/mole

1.If 5.00g of iron is produced, how much iron (III) oxide (in grams) was placed in the original container?

2.If 5.00g of iron is produced, how many particles of aluminum were placed in the original container?

3.If 5.00g of iron is produced, how much heat is released or absorbed?

NaOH +HCl ? NaCl + H2O ?H = -5624 kJ/mole

4.If 5.00g of water is produced, how much HCl (in grams) was placed in the original container?

5.If 5.00g of water is produced, how many particles of NaOH were placed in the originalcontainer?

6.If 5.00g of water is produced, how much heat is released or absorbed?

7.If 5.00g of water is produced, what is the concentration of NaOH if 75mL was fully reacted?
